The modern medical ketogenic diet was created and named by Dr. Russell Morse Wilder at the Mayo Clinic in the early 1920s, building on earlier fasting- based epilepsy treatments. He designed the high-fat, very low‑carb regimen to mimic the metabolic effects of fasting while being sustainable long term for people with epilepsy.

Quick Scoop

  • The idea of using fasting for epilepsy goes back to early 1900s “physical culture” advocates like Bernarr Macfadden and Dr. Hugh Conklin, who noticed seizures improved when patients fasted.
  • In 1921, Wilder studied how low‑carb, high‑fat eating produced ketones similar to fasting and coined the term “ketogenic diet.”
  • Shortly after, pediatrician Mynie Gustav Peterman at Mayo standardized the classic keto formula (about a 4:1 fat to protein+carb ratio) that is still the medical template today.
  • The diet was originally a therapy for childhood epilepsy , not a weight‑loss fad, and only much later became trendy for weight loss and metabolic health.

So who “created” keto?

If someone asks “who created the keto diet,” the historically accurate answer is:

  • Dr. Russell M. Wilder (Mayo Clinic, 1921–1923)
    • First to formalize a high‑fat, very low‑carb diet specifically to induce ketosis for epilepsy treatment.
* First to label it the **ketogenic diet** in the medical literature.

However, several people shaped what most people now call “keto”:

  • Pre-keto groundwork
    • Bernarr Macfadden popularized therapeutic fasting in the early 20th century.
* Dr. Hugh Conklin used prolonged fasting to treat epilepsy, inspiring formal research into diet and seizures.
  • Refinement of the classic keto diet
    • Dr. Mynie Gustav Peterman at Mayo standardized the pediatric protocol (4:1 fat to protein+carb, ~90% of calories from fat).
* In the 1960s–70s, Dr. Peter Huttenlocher developed the **MCT (medium‑chain triglyceride) keto diet** , allowing more protein and carbs with similar ketone production.

From epilepsy clinic to trending diet

  • Through the mid‑20th century, keto was mainly a niche therapy for drug‑resistant childhood epilepsy , and its use declined as new seizure medications appeared.
  • In the 1990s, the Charlie Foundation (founded by film producer Jim Abrahams after his son’s epilepsy improved on keto) triggered a major revival of medical interest.
  • From the 2000s onward, researchers and popular books began promoting ketogenic and very low‑carb diets for obesity, type 2 diabetes, and metabolic syndrome , helping push keto into mainstream diet culture.

Forum / “latest news” angle

In online forums and recent nutrition discussions, people often:

  • Credit Wilder and the Mayo team for the original medical framework , while noting that today’s “lazy keto” or “dirty keto” for weight loss is a looser interpretation.
  • Debate whether modern keto is closer to:
    • The strict 4:1 clinical version (used in epilepsy centers), or
    • A flexible low‑carb, high‑fat lifestyle that borrows the name but not the exact ratios.

Recent academic and clinical reviews continue to trace the diet’s origin back to Wilder in the 1920s while exploring new uses (diabetes, neurological disease, cancer adjunct therapy), so the historic “creator” attribution has not changed.

TL;DR: The fasting idea is older, but the ketogenic diet as a named, structured therapy was created by Dr. Russell M. Wilder at the Mayo Clinic in 1921–1923 , then standardized by colleagues like Mynie Peterman and later modified by Peter Huttenlocher.
